In Chrome, I could drop correctly .txt, .apk and .img files into my web but not Mac .app file , while they all could be dropped correctly in Safari.

I did console.log(event.dataTransfer.files) in drop listener. All of the .app file would be the same obj:

lastModified: 1577865600000
lastModifiedDate: Wed Jan 01 2020 02:00:00 GMT-0600 (Central Standard Time) {}
name: {fileName}
size: 96
type: ""
webkitRelativePath: ""

In Safari, the .app file would be converted to a zip file and the file could be dropped correctly.

1. Why is this the case?
2. What is the best way to fix this behavior?
3. Any other file type would behave the same as .app?
